The Piececlopedia is intended as a scholarly reference concerning the history and naming conventions of pieces used in Chess variants. But it is not a set of standards concerning what you must call pieces in newly invented games.

The Piececlopedia: Amazon

Historic remarks

The Amazon was invented (but not under this name) in the middle ages.
At certain places in Europe, one experimented with this piece instead of
the Queen, trying out how to replace the old slow Ferz by a more powerfull piece. Dickins mentions four names for this piece: Omnipotent Queen, Terror, General, or Amazon. He also mentions that it was used before 1500 A.D. It's most common name these days is Amazon.

Oh, I see. For example RookKnights on the a-file, and Amazons on the
h-file. Sure, that's good stuff. All double and triple compound pieces
can be used that way- 2 at a time as above, or even 4 at a time,
replacing
4 of the rooks knights and bishops in the original line up.
By the way, I dislike using 6 new pieces. For example a- file cardinals,
b-file squirrels, c-file amazons, f-file centaurs, g-file RookKings, and
h-file BishopKnightKings or whatever. The problem with 6 new pieces, in
my
humble opinion, is that too many basic chessmen are eliminated from the
game.
New pieces are great, but the interaction of the basic pieces with the
unorthodox pieces is interesting, entertaining, and not to be missed.
I always like to keep the queens in the starting array for this reason.

Stve misses the point, in that David Paulowich is suggesting substituting for two different pieces. Both players would have their army enhanced by adding a Knight move to exactly one piece, but in one case it would be the Queen itself and the other the Queen's Rook.
